- Accuracy up to +/- 0.10% error - application engineered
- Designed for minimal material build up
The principal of the Closed Space Roller Rack (CSRR) design is to improve accuracy by reducing the ratio of angular misalignment effect of the tensioned belt. This is achieved through an increased effective weigh length and significantly reduced material and belt agitation within the transition of material into and out of the weigher zone.
This system is able to provide 0.1% repeatability for periods of up to 12 months without recalibration and has demonstrated itself as the only system on the market capable of this level of accuracy.
CST’s CSRR variant usually come in a Non-Intrusive design. This is a weightometer that can be installed to a conveyor without the need for modification of the conveyor structure.
The installation of any industry standard beltweigher to a conveyor structure would require the removal of angular bracing, cross bracing and any other structural steel located within the conveyor section where the beltweigher is to be located. Removal of structural steel potentially weakens the conveyor and requires re-engineering of the truss or conveyor modules.
CST’s Non-Intrusive beltweigher is designed to sit above any variation of conveyor without the need for removal of structure, saving on required site modification work and re-engineering costs.
